Cool,

I'm one day late for this april fool :

It could be axiom that build a good amp to power your sub and dissipate that much heat in your room.
Do you know they take care of customers at winter period ?
When you pay for an axiom sub it's way more than for listening music.
You should thanks them.
Subs are in fact electric radiators.
They own contracts with a radiator company :p

Look at computer graphic cards, it's same story :p
